UAX #14: no line breaks between OP and QU, even if there are intervening spaces

In UAX #14, rule LB15 states "Do not break within ‘”[’, even with  
intervening spaces." This is formalised as

    QU SP* × OP

What is the rationale behind this rule?

I can't think of any example where breaking at the intervening spaces  
would create undesirable results, whereas NOT breaking at the intervening  
spaces will tend to break up very short quotations in favour of keeping  
the trailing end of the quotation together with a following parenthetical  
remark.

As an example, given a sufficiently small text area width, the algorithm  
will break text this way:

    "The
    Wire" (2005)

but never this way:

    "The Wire"
    (2005)

which is IMHO more logical.
